This is the stuff they are benchmarking for:

http://github.com/MadRabbit/taskspeed/blob/master/tests/jq-t...

There is literally no isolation between what is being tested and how much performance goes into unrelated operations.

Example: The test for the bind operation executes the "ul > li" selector before performing the bind, thus the results are affected by this.

I could be wrong, but it seems like a benchmark specifically tailored to the benefit of RightJS and it provides no indication for overall performance of RightJS based applications.

RightJS might be wicked fast for all I know, but this test suite is not going to convince me.
